Different kinds of internal conflicts include

Personal flaws
This is the innermost internal conflict. It is related to the physical appearance and makeup, internal morphology and psychological makeup of the main character. It is also related to his behavioral pattern.
If the biology of any of these mentioned above is not in order, the main character feels incomplete. And once he finds out that his incomplete nature affects his fight against the opposition, he feels depressed and conquered.
Bearing in mind the responsibility vested in him, he rises to make himself complete. He faces himself to fix whatever thing wrong with him.
If he is illiterate, he tries to acquire some education.
If he doesn't have a fighting skill, he rushes to get one.
If he is sick, he quickly seeks medical attention.
If his face is deformed, he can go for a plastic surgery.
Getting himself to be normal all gears towards getting himself ready and fully equipped for the main fight.

The definition of a hero is the character who is always in a fight against evil throughout the course of the screenplay.
There is nothing to watch in a movie if the story is all about idleness, comfort, enjoyment, peace, indolence and irresponsibility on the part of the hero. A movie is all about the repeated emergence of problems and repeated fights by the hero against the problems.
